Jan 07, 2025 am 11:41 AMFormatting Excel Columns to Decimal During Export from C#
Question:
While exporting database data to Excel using C#, numbers in specific columns are displayed as integers instead of decimals (e.g., 5 instead of 5.00). How can I programmatically format these columns in decimal format on the C# side?
Additionally, I would like to merge specific header cells and format them as bold, gray with uppercase text.
Answer:
To format specific Excel columns as decimals during export, you can use the following code:
Response.Write("<td>"); Response.Write(String.Format("{0:0.0#}", dr["EstimatedPriceTotal"].ToString())); Response.Write("</td>");
The code above uses the String.Format method to format the EstimatedPriceTotal column using the 0.0# decimal format specifier. This will ensure that the value is displayed with two decimal places.
To merge and format header cells, you can use the following code:
Response.Write("<tr>"); Response.Write("<th>"); Response.Write("<span>CustomerName</span>"); Response.Write("</th>"); Response.Write("<th>"); Response.Write("<span>Mitesh Jain</span>"); Response.Write("</th>"); Response.Write("</tr>");
This code creates a header row with two cells merged together. The text in the merged cells is wrapped in a tag to allow it to be formatted separately.
Finally, here's a complete example that includes both the decimal formatting and the header formatting:
Response.Write("<tr>"); Response.Write("<th>"); Response.Write("<span>Actual Estimated Price</span>"); Response.Write("</th>"); Response.Write("<th>"); Response.Write("<span>Aprroved Estimated Price </span>"); Response.Write("</th>"); Response.Write("<th>"); Response.Write("<span>Actual Price</span>"); Response.Write("</th>"); Response.Write("<th>"); Response.Write("<span>Aprroved Actual Price </span>"); Response.Write("</th>"); Response.Write("<th>"); Response.Write("TransactionID </th>"); Response.Write("</tr>"); foreach (DataRow dr in dt.Rows) { Response.Write("<tr>"); Response.Write("<td>"); Response.Write(String.Format("{0:0.0#}", dr["EstimatedPriceTotal"].ToString())); Response.Write("</td>"); Response.Write("<td>"); Response.Write(String.Format("{0:0.0#}", dr["ApprovedEstimatedPriceTotal"].ToString())); Response.Write("</td>");

Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.

C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.

Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
